Embodiment 1
[0008] A heat treatment process for a PS plate base with excellent electrical corrosion performance. The process content is: the plate is hot-finish-rolled to a thickness of 4.5mm, and then cold-rolled to a thickness of 0.9mm. For this thickness, the plate is first heated to 600°C and then heated. The speed is 100°C / h, and the temperature is kept for 2.5-3.5 minutes, air-cooled to room temperature, and then cold-rolled to 0.27mm.

The invention discloses a heat treatment technology of an aluminum-based PS board. The technology is as follows: firstly carrying out hot finishing on the board until the thickness is 4.5mm, then carrying out cold rolling until the thickness is 0.9mm, heating the board with the thickness of 0.9mm to 600 DEG C with the heating speed of 100 DEG C / h, preserving heat for 2.5-3.5min, cooling air to room temperature, then carrying out cold rolling until the thickness is 0.27mm. The invention has the advantages that by the heat finishing technology, fine and even crystal grains of the baseboard can be generated, and the impurity phases in the matrix are fine and have uniform distribution. The corrosion current has larger density and fast speed, and the corrosion holes are evenly distributed, thus well ensuring to generate fine and evenly distributed grains.
Description
technical field [0001] The invention relates to a heat treatment process, in particular to a heat treatment process for an aluminum-based PS plate. Background technique [0002] Aluminum-based PS plate is currently the most common main consumable for offset printing. Its preparation method generally uses electrochemical corrosion to prepare grains on the surface to improve the adsorption and hydrophilicity of the plate base to meet printing requirements. The electrical corrosion performance of the aluminum plate base directly affects the quality of the PS plate. At present, domestic PS plate products mainly have problems such as coarse grain, uneven grain layer, and uneven thickness of oxide film, which seriously restrict the development of PS plate in China. Contents of the invention [0003] The object of the present invention is to provide a heat treatment process for a PS plate base with excellent electric corrosion performance. [0004] For this reason, the technica...
